Application filed April 18, 1917. Serial No. 162,953.

To all whom it may concern:

Be it known that I, IRVING C. RATHBUN, a citizen of the United States, residing at tors; and I do hereby declare the following to be a full clear. and eXact descri otion of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in tools, and pertains more particularly to tools of the pliers type.

The primary object of the present inven tion is to provide a tool by the use of which cotter pins may be removed from shafts or the like.

A further object of the invention is to construct a device for removing cotter pins in which means is provided for engagement with the eye of the cotter pin.

A further object of the invention is to so construct adevice for removing cotter pins that means for imparting leverage to the tool is provided during its operation.

Referring to the drawings,

Figure 1, is a side elevation of the device,

Fig. 2, is an end view thereof,

Fig. 3, is a side view showing the method of operation, and,

Fig. at, is an edge view of the device.

Referring more particularly to the drawings, the device comprises a pair of crossed handles 5 and 6 each of which is provided with an enlarged portion 7 which is perforated as at 8, and passing through the perforations 8 in the enlarged portion 7 is a pin or the like 9 which serves to pivotally secure the crossed handles 5 and 6 together. The handle member 6 is reduced beyond its pivoted point at at 7 and is provided at its end with a r ght angular projection 10 which is preferably circular in cross section.

The handle member 5 beyond its pivot is curved as at 11 on its outer edge, and said handle member 5 terminates in a right angular projection 12 which is adapted to lie in a plane at right angles to that of the member 10. The right angular extension 12 of the handle member 5 is of such length that when the handle members 5 and 6 are spread apart, the right angular extension 10 of the handle member 6 will pass to a point beyond the free end of said right angular extension 12.

When the parts are in this position, the rightangular extension 10 of the handle member 6 is engaged in the eye 13 of a cotter pin 14:. After this step has been taken, the handle members 5 and 6 are brought together to the position shown, and the right angular member 10 in the handle member 6 lies in relatively close relation to the right angular extension 12 of the handle member 5 but in a plane at right angles thereto. It will. thus be seen that the cotter pin is prevented from accidental displacement from the right angular extension 10. If now the end of the member 12 be engaged with the shaft, and the handle members moved together it will be seen that the cotter pin will be removed from the shaft, the member 12 forming a fulcrum for the pliers in their operation.

From the foregoing it will be seen that the present invention provides a tool by the means of which cotter pins and the like may be readily removed from the openings in which they are engaged without in any \vaf, damaging or distorting the cotter pins, and by reason of the relative position of the right angular members 10 and 12, the tool is at all times engaged with the cotter pin when the handle members 5 and 6 are in relative close relation.

Having thus described the invention, what is claimed is:

1. A device of the character described comprising a handle member terminating at one end in an angularlv projecting portion, second handle member pivoted to the first mentioned handle member and having a re duced end having is extremity terminating at right angles thereto, the right angular portion of the last mentioned handle member lying in a plane at substantially right angles to the angularly projecting portion of the first mentioned handle member.

2. A device of the character described comprising a handle member, a portion projecting at an angle from one end of the handle member, a second handle member pivoted to the first mentioned handle memher, and provided with a reduced end, and In testimony whereof, I aflix my signature a member pfiojecting frclgm said redlllced enld in the presence of tWo Witnesses,

of the said ancle mem er at a rig it ang e thereto, said right angular projecting mem- IRVING RATHBUN" 5 her lying in a plane at substantially right Witnesses:

angles to the angular projecting portion of H. B. CARLEToN,

the first mentioned handle member. WV. C. Corns.
